There are two methods for clinker pretreatment: precrushing and pregrinding. 1) The precrushing uses a crusher to crush the clinker before grinding, which can reduce the diameter of the clinker particles to 5 ~ 8mm. 2) The pregrinding adds a roller press to the cement grinding system.

SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action.
